+STMicroelectronics STi System Configuration Controlled IRQs
+-----------------------------------------------------------
+
+On STi based systems; External, CTI (Core Sight), PMU (Performance Management),
+and PL310 L2 Cache IRQs are controlled using System Configuration registers.
+This driver is used to unmask them prior to use.
+
+Required properties:
+- compatible : Should be set to one of:
+ "st,stih415-irq-syscfg"
+ "st,stih416-irq-syscfg"
+ "st,stih407-irq-syscfg"
+ "st,stid127-irq-syscfg"
+- st,syscfg : Phandle to Cortex-A9 IRQ system config registers
+- st,irq-device : Array of IRQs to enable - should be 2 in length
+- st,fiq-device : Array of FIQs to enable - should be 2 in length
+
+Optional properties:
+- st,invert-ext : External IRQs can be inverted at will. This property inverts
+ these IRQs using bitwise logic. A number of defines have been
+ provided for convenience:
+ ST_IRQ_SYSCFG_EXT_1_INV
+ ST_IRQ_SYSCFG_EXT_2_INV
+ ST_IRQ_SYSCFG_EXT_3_INV
+Example:
+
+irq-syscfg {
+ compatible = "st,stih416-irq-syscfg";
+ st,syscfg = <&syscfg_cpu>;
+ st,irq-device = <ST_IRQ_SYSCFG_PMU_0>,
+ <ST_IRQ_SYSCFG_PMU_1>;
+ st,fiq-device = <ST_IRQ_SYSCFG_DISABLED>,
+ <ST_IRQ_SYSCFG_DISABLED>;
+ st,invert-ext = <(ST_IRQ_SYSCFG_EXT_1_INV | ST_IRQ_SYSCFG_EXT_3_INV)>;
+};
